TRANSLATIONAL sEo'rmnAL-MoLn ASSEMBLAGE.

Application filed api-n 7,

and useful Improvementsin Translational following is a specification.

My invention relates toimpro-veinents in translational sectional mold assemblages, and the object of my improvement is to furnish sectional molds for. concrete blocks with mechanism of which certain sections of said molds are elements, the mechanism being; operative to propel the assembled molds through a determined distance t-hen to automatically disassemble the molds while delivering; the newly molded blocks.

This object I have accomplished by the means and mechanism which are hereinafter described and claimed and which are illustrated in the accompanying drawings, in which Fig. 1 is a vertical longitudinal section of said invention taken on the broken line l-lof F ig. 2, and Fig. 2 is a top plan of the invention with parts rc moved. or broken away. Fig". 3 is an enlarged view of linked assembled molds with parts shown in side elevation and other parts in longitudinal vertical section or broken away. Fig. 4 is a top plan View of linked parts of the mold and carrier elements, with parts removed or in section. Fig, 5 is a cross section taken on the broken line 5-5 of said Fig. 3, and Fig. 6 is another cross section taken on the broken line 66 of saidFig". 3. Fig. 7 is a perspective view of the bottom pallet oi a mold.

The mechanism of my invention may be operatively mounted and supported in any desired supporting frame or construction, but I have not shown any such construction, in order to afford a better disclosure of themechanism and of the associated mold assemblages, H

The purpose of my invention is to supply translational sectional molds, in which, while assembled. blocks or objects may be formed or molded, of any kind or shape desired, but in the instance illustrated, to mold or shape building-blocks of cement. concrete or other materials, propelling and delivering them as" formed successively.

These molds when assembled. are linked together in alinement, but the molds are Sectional-Mold Assemblages, of which the 1922. serialno. 550,539.

alike and each constructed of sections to provide an open top closed bottom hollow structure.

Each'mold comprisesa bottom pallet 8, fiat, but which may be of any desired con- ,iiguration the one shown in Fig, Tbeing imperforate, oblong, and having at each "end diminishing'notches or'cut out openings 15, while preferably. though not necessarily having a plurality of depending short end. and side legs 9 and 14 respectively, these being useful, after the, pallet and newly formed block thereon are delivered"disassembled from the other parts i of the mold, in supporting the pallet on a, I

surface raised thereabove to permit ot' easy manual handling; and lifting; oi the pallet and block.

Theside-walls let each mold are imperforate, oblongpand have at theirends, hinge-connections 3 with the ends of the" alined abut-ting walls 1 of other molds. The pmtle of each pair. of hinge-connectrons 3 is carried across their. interspaceto serve as a pintle also for a vertical roller 2 without the mold. at the bottom of its inner face a pair of short ledges 4 upon which the pallet8 is supported removably.

I have supplied mechanism for translat- Each section 1 has in one direction said interlinked molds.

This includes a sprocket-chain of peculiar construction. having spacedpairs of linkbars 6 which are rigidly connected by several cross-rods 5 and 13,. the ends of each rod 5 projecting outwardly and serving to underlie and su'pportthe side-sectrons 1 o f said molds. pair of link-bars (B the bars are brought At one end of each converging-1y nearer together to fit between ends of the adjacent pair of link-bars. and

a pintle 33 connects said bars midway between pairs of cross-rods 13, a roller 7 being rotatably mounted. on said pintle.

Referring to sa-idFig. 3, the numeral 12 denotes a p-yamidal hollow structure formed of sheet metal. of which opposite lowerend JilltS are sha Jed as sleeves enclosin a pair of cross-rods 13 between said link-bars 6, whereby each pyramid 12 or' as it will be hereinafter termed end-former is rigidly mounted between the link-bars. It will also be now observed that each of the endformers 12 serves as a projection for propellinp; the molds in one direction coinci dent with the movement in said direction of the link-bars 6 of said sprocket-chain. "When the end-former 12 is positioned as shown in Fig. 3 to become a part of the mold assemblage, it fits into the enclosing notch 15 of the pallet 8 and between the inwardly projecting sloping ribs 16 of the within the molds I in said molds may have trough-shaped hol- 'less side-walls 1, whereby an end-wall is provided for the mold adapted to form a reentrant recess in block 10 molded therein. Like sprocket-wheels 26 and 28 are fixed rigidly on rotatable horizontal shafts 25 and 27 respectively, and have end-notched teeth to receive the rollers of the link-bar chain 6. V H I I At opposite sides of the link-bar chain 6 are positioned pairs of vertical rotatable shafts 17 and 21, and'each pair having fixed thereon like sprocket-wheels 20 and 22 respectively with end-notched teeth which receive the said rollers 2 on the mold sidesections 1. On one shaft 17 is fixed a beltwheel 18 carrying a driving-belt 19..

Thenumeral 23 denotes a like pair of side guides or bars positioned along the side- .walls of the molds to be contacted by the side-rollers 2 to keep the sides 1 in place' while the molds are being filled in the making of said blocks, and the delivery ends of the'bars23 are made divergent to permit the linked parts 1 to be carried around the sprocket-ivheels 20, while releasing the newly formed blocks, which are transported by the and 31, the latter carried by rollers 30 on a rotatable shaft 29, a fixed supporting table 32 being placed under the upper reach of said band 31. to support the superincumbent blocks.

any desired means may be supplied to position pallets 8 upon the lugs i of the advancing side-plates 1 successively. The mold-plates or sections 1 become disassembled at the delivery ends of the guides 23 i and 2%, so that the pallets 8 and the blocks 10 thereon only are delivered upon the endless carrier 31.

In mechanism of the character described, separably assembled sectional molds open at the ends, translational devices therefor having driving projections insertible between the molds to close their ends and to suitably shape the ends of blocks formed in the molds, and means for holding said moldsections in engagement during a determined part only of their movement of assembled translation.

In mechanism of the character described, separably assembled and engaged mold-sections, a plurality of translational devices operatively connected with diiferent like alined mold-sections for simultaneous coaction therewith, and guides for maintaining said mold-sections in a desired rela tion during a part only of their translatory movement as an assemblage, certain of said mold-sections serving as pallets and automatically separating from the other mold-sections when said assemblage has left said guides, and shaper elements of the molds mounted on certain of said translational devices and withdrawable from the molds at a certain stage of movement of said devices.

In mechanism of the character described, separably assembled and engaged mold-sections, a plurality of translational devices operatively connected with different like alined mold-sections for simultaneous coaction therewith, certain of said mold-sections shaped to interlock and serving as pallets and block-forming end-closures and automatically separating from the other moldsections at certain successive stages of move ment of said translational devices.
